发明名称 AIR DUCT COMPONENT, SUCTION OPENING AND VACUUM CLEANER
摘要 PROBLEM TO BE SOLVED: To provide a floor brush capable of preventing a sound produced by ventilation. SOLUTION: An air duct 52, the sectional area of which is gradually decreased toward the lee side, is provided in the body portion 53 of an air duct component 51. A rib piece 55 rectifying intake air passing through the air duct 52 is provided in the air duct face 54 of the body portion 53. Intake air sucked from the nozzle 35 of a case 31 of a floor brush 26 passes through the air duct 52 of the air duct component 51. A turbulence caused by the collision of intake air with the air duct face 54 passing through the air duct 52 decreases. A sound produced by the passage of intake air through the air duct 52 of the air duct component 51 can be prevented.
